Description

• Friend based ad hoc routing using challenges to establish security is an algorithm to provide secure routing in ad hoc mobile networks. • The name of the algorithm is FACES which stands for friend based ad hoc routing using challenges to establish security. • The FACES algorithm is divided into four stages. Such as challenge your neighbor, rate friends, share friends and route through friends. • The algorithm works by sending challenges and sharing friend lists to provide a list of trusted nodes to the source node through which data transmission finally take place. • The nodes in the friend list are rated on the basis of the amount of data transmission they accomplish and their friendship with other nodes in the network. • It is used to collect the information about the malicious nodes effectively by using challenges. • Also it’s reduces the overhead on the network significantly.
